NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 301,870, dated Julyl, 1884.

Application sled Aprile, 1884. (Nq model.)

Zo @ZZ whom it may concer-r1,.-

Be it known that I, MILLARD F. DILLoN, a citizen of the United States, residing at Gillespie, in the county of Macoupin and State 1 of Illinois, have invented a new and useful Nut-Lock, of which the following is a specifil cation, reference being had to the accompanying drawings.

My invention relates to nut-locks; and it has for its object to provide a device of, this character which shall possess superior advantages in point of simplicity, durability, and general efficiency.

'With these ends in view the invention con-y to be connected together, the same being provided wit'h suitable openings for the passage of the securing-bolts.

B represents the fish-plate, which is locate on the outer sides of said rail-sections, toconneet the joint thereof. This sh-plate is provided at its lower end with an outturned portion or ilange, C, and is provided with suitable openings, which register with the openings of the said rail-sections.

D represents the securing-bolts, which are adapted to pass through the vopenings of the rail-sections and ofthe fish-plate, which, as before mentioned, register with one another,Y and of which there can be as many as may be desired or found necessary. Upon the two end securing-bolts of each section are provided locking-plates E, which are held in position upon said bolts by means of nuts b. These locking-plates E are provided at their outer ends with outwardly-extending iianges G G', the flange G being provided with a notch or recess upon its under side, while the iiange of the adjacent locking-plate is provided with a similar notch or recess on its upper side.

I-I represents the locking-bar, one end of which is inserted in the notch or recess of the flange G, and which rests upon the ange G of the fish-plate B, and bears against the securing-nuts upon their under sides. The other end ofthe locking-bar H is bent upwardly and engaged with the notch or recess dof the flange G. The end may be then bent downwardly to secure the saine. first passed through thc usual openings in the rail and the iish-plate. 'Ihe locking-plates E are then adj usted upon the bolts, and the nuts placed on said bolts and tightened. The locking-bar is then inserted, one end through the opening c of the flangel of one locking-plate, and then passed below the under side of the nuts, and rests upon the flange' C. The other or bent end is forced upwardly and slid into the slot el in the flange G of the other lockingplate. Y

By this construction of nut-lock it will be readily seen that all possibility of the nuts becoming loose, and their consequent detachment, is prevented.

It will be further apparent that my improved nut-lock is simple in its construction, readily applied, and that it affords effective and serviceable means for the purposes for which it is designed.

Having fully described my invention, what vI claim as new, and desire to secure by Letters Patent, is-

l. In a nut-lock, the combination, with a sh-plate provided at its lower end with an outwardly-extending liange, of locking-plates adapted to be secured kupon the securing-bolts, said locking-plates being provided at their outer ends .with fianges, and a locking-bar adaptedto engage the same, substantially as set forth.

2. In a nut-lock, the combination, with a 'sh-plate provided at its lower end with an outwardly-extending flange, of locking-plates mounted upon the securing-bolts and provided at their outer ends with outwardly-projecting iianges, one of said flanges being provided with a notch or recess upon its under side,

while the other ange is provided with a simiy lar notch orrecess upon its upper side, and a locking-bar adapted to engage the same, as set forth.

3. In a nut-lock, the combination, with a The bolts are IOO secure the nuts against displacement, its other end being bent upwardly to engage the notch or recess of the other innige, :is set forth.

In testimony that I claim the foregoing as 15 my own Ihave hereto aiixed my signature in presence of two witnesses.

MILLARD FILLMORE DILLON.
